Chapter 9

now seeks to make clear to the student the dramatist's method of character portrayal. A third hour may be spent on certain portions of this act in which attention is given to significant facts of language, choice of words, or poetic form. When a guiding aim controls, all questions, suggestions, explanations, and illustrations tend to create in the mind of the pupil a rich and unified impression. Where no distinct aim gives direction to the work, the student is confused by a variety of facts--isolated facts--that are displaced by another group of disjointed bits of information. Aimless teaching leads to mental wandering on the part of the student; teaching governed by a definite aim leads to mental development and to the acquisition of new viewpoints and new power.

=The educational aim vs. the instructional aim=

We must distinguish clearly between the general or educational aim and the specific or instructional aim. The former sums up the hope of an entire course or an entire subject. In the teaching of literature we hope to develop a vital interest in reading, a discriminating taste, an enlivened imagination and a quickened perception which enable the student to visualize the situations and to acquire the thought on the printed page. The instructional aim, however, is much more specific; it posits a task that can be accomplished in a very limited time; it seeks to give an insight into Shakespeare's mastery of words, or into his power of character portrayal, or into his methods of enhancing dramatic interest. Each of these two types of aims has its unmistakable influence on methods of teaching.

=The variety of aims that may govern teaching=

What aim should we select to guide us in formulating principles of collegiate teaching? The question is almost basic, for the selection of a proper aim gives color and direction to all our teaching. In brief, the aim may be one of the following:

(_a_) _The informational aim._ A given course in chemistry or physics may be designed to sum up for the student the vital facts necessary for an intelligent comprehension of common phenomena. With such an aim, it is obvious that only so much laboratory work will be assigned as will give the student a general knowledge of the tools and methods of laboratory work; that the major portion of the work will be divided into occasional lectures, regular book assignments, and extensive applications of knowledge gained to surrounding chemical and physical phenomena. A language course may seek to give pupils a stock of words designed to develop power to read the language in a very short time. Obviously, grammatical work and translations into the mother tongue will now be minimized, and those devices which give the eye the power to find thought in new symbols will be emphasized. There is no standard for determining the relative importance of this informational or utilitarian aim when compared to other aims. The significant thing is, not so much to discover its relative importance, but, having adopted it, to devise methods which clearly tend to bring the students to an effective realization of it.

(_b_) _The disciplinary aim._ On the other hand, the controlling aim in any subject may be to develop the power to reason about natural phenomena, the power to observe, and the power to discriminate between vital and inconsequential details. If this be the aim, the assignment of subject matter must be reduced, the phenomena studied must be submitted in the forms of problems, first-hand observations must be made, and students must be led to see the errors in their observations and their reasoning. The course which is extensive in subject matter and which relies on the lecture method sacrifices mental discipline for information. From the teaching point of view, the result of the time-honored quarrel between the disciplinists and the utilitarians is not so important as the adoption of a definite aim, and the formulation of consistent methods of teaching in order to attain that aim. Ineffective teaching is not caused by the selection of the one aim or of the other, but by systems of instruction devoid of any aim at all.

(_c_) _The appreciative or æsthetic aim._ It is obvious that a subject may be taught for the power it develops for æsthetic appreciation of the arts of life. We have here a legitimate aim of coördinate importance with the two preceding ones; and if we adopt it, the vital thing in teaching is to allow this appreciative aim to mold all instructional effort. It is obvious that a college course in æsthetics must be inspirational, must seek to develop a real appreciation of the beauty of line, of color and of sound. Such a course must, therefore, encourage contact with the products of art, rather than promote the study of texts on the history of any of the arts. So, too, courses in music or in literature which do not send the student away with an intense desire to hear, to see, to feel the masterpieces of music or literature must be judged dismal failures. The formalization of an art course given to the general student, kills the live material and leaves the student himself cold.

(_d_) _The aim to teach technique._ An effective college course may select for its aim the development of the technique of a given subject. It is obvious that a science course governed by this aim will emphasize the laboratory method at the expense of information; that a course in the social sciences will seek to cover less ground but will develop in the student the power to find facts and use them to formulate an intelligent conclusion; that a course in biology will minimize names, classifications and structures, but will emphasize field and laboratory work and the modes of utilizing the data thus discovered. We must repeat the statement made before, that no one can set himself up as the final arbiter of the claims of these contending aims. They are all vitally necessary for a thorough understanding of life's problems. The significant conclusion for teaching is that one or more of these aims must be consciously chosen and that content and method must be determined by them absolutely. Teaching for the sake of teaching consumes time and makes drafts on energy, but it leaves the student no richer in power and with no truer understanding.

=Should the aim be modified for varying groups of students?=

It is obvious that no general law can be formulated for the adjustment of aims to the needs of students. Teachers have usually found it necessary to change the aim, the content, and the method of a course according to the needs of different classes of students. In one of our colleges science students are required to take two years of Latin. The course offered these young men gives the ordinary drill in grammar, translation, and analysis of Cæsar, Cicero, and Vergil, as well as practice in prose composition in which nondescript and disjointed English sentences, grammatically correct, are turned into incorrect Latin. This description, without any changes whatever, applies also to the course given in the introductory years in Latin to students specializing in the arts. Even a superficial analysis reveals a different set of needs in the two classes of students which can be served only by a corresponding difference in content and mode of teaching. A student who takes French or German because he wants enough mastery of these languages to enable him to read in foreign journals about the progress of his specialty must be given a course which appeals to the eye and minimizes the grammatical and conversational phases of these languages.

There are courses that are foundational and that must therefore be governed by an eclectic aim. In the first course in college physics it is obvious that we must teach the necessary facts of the subject as well as its method. These aspects of the work must be emphasized with equal force for all students; no differentiation need be made for future medical or engineering students or for prospective teachers of the subject in secondary schools. Generally speaking, initial courses in a department are governed by an eclectic aim, but in the advanced courses there must be constant adjustment to the needs of various groups. An eclectic aim can be as effective an instrument in enhancing the quality of teaching as a single, clear-cut aim, provided there is a clear recognition of the relative importance of the ends set up, and provided a definite plan is evolved to attain them.

The aim or aims of a subject or a lesson, once formulated, must always be kept before the students as well as before the teacher. Every pupil must know the ends to be attained in the course he is taking, and as work progresses he must experience a growing realization that the class is moving toward these ends. The subject matter of the course, the method of instruction, the assigned task, now glow with interest which springs from work clearly motivated. The average student plods through his semester from a sense of duty or obedience rather than from a conviction of the worth of both subject matter and method.

=Value of clearly defined aims=

Not only must the general aim be indicated to the student, but he must also be made acquainted with the specific aim. Where students have been acquainted with the specific task that must be accomplished in a given period, concentration and coöperation with the instructor are easier; the students can, at stages in the lesson, anticipate succeeding steps; their answers have greater relevancy, their thought is more sequential and flows more readily along the path planned by the instructor. A specific aim for each lesson makes for economy, for it is a standard of relevancy for both student and teacher. The student whose answer or observation is irrelevant is asked to recall the aim of the lesson and to judge the pertinence of his contribution. The instructor given to wandering far afield finds that a clearly fixed aim is an aid in keeping him in the prescribed path. Too many college hours, especially in the social sciences, find the instructor beginning with his subject but ending anywhere in the field of human knowledge. These wanderings are entertaining enough, but they dissipate the energies of the students and produce a mental flabbiness already too well developed in the average college student.

=Motivation in college teaching=

A second factor which contributes much toward the effectiveness of college teaching is the principle of motivation. So long as most of the college course is prescribed, course by course, students will be found pursuing certain studies without an intelligent understanding of their social or mental worth. Ask the student "doing" prescribed logic to explain the value of the course. In friendly or intimate discussion with him, elicit his conception of the utilitarian or disciplinary worth of the prescribed Latin or mathematics in the arts course. He sees no relation between the problems of life and the daily lessons in many of these subjects. He submits to the teacher's attempts to graft this knowledge upon his intellectual stock merely because he has learned that the easiest course is to bend to authority. Instruction in too many college subjects is based, not on intelligent and voluntary attention, but on the discipline maintained by the institution or by the instructor. It is obvious that such instruction is stultifying to the teacher and can never develop in the student a liberal and cultured outlook upon life.

The principle of motivation in teaching seeks to justify to the student the experience that is presented as part of his college course. It is obvious that this motivation need not always be explained in terms of utilitarian values. A student of college age can be made to realize the mental, the cultural, or the inspirational values that justify the prescription of certain courses. The college instructor who tries to motivate courses in the appreciation of music or painting finds no great difficulty in leading his students to an enthusiastic conviction of their inspirational value. It is well worth taking the student into our confidence in these matters of aim and value. We must become more tolerant of the thoughtful student who makes honest inquiry as to the value of any of the presented courses. We must learn to regard such questions as signs of growing seriousness and increasing maturity and not as signs of impertinence. We constantly ask ourselves questions about the round of our daily task; we seek to know thoroughly their uses, their values, their meaning in our lives. Clear conception of use or value in teaching is as vital as it is in life--for what is teaching if not the process of repeating life's experiences?

In the principle of motivation lies the most successful solution of the problem of interest in teaching. We have too long persisted in the "sugarcoating" conception of interest. We have regarded it as a process of "making agreeable." Interest has therefore been looked upon as a fictitious element introduced into teaching merely to inveigle the mind of the student into a consideration of what we are offering it. Our modern psychology teaches a truer conception of interest: a feeling accompanying self-expression. Interest has been defined as a feeling of worth in experience. Where this feeling of worth is aroused, the individual expresses his activity to attain the end that he perceives. Every act, every effort, to attain this end is accompanied by a distinctive feeling known as interest. When a class is quiet and gives itself to the teacher, it is obedient and polite, but not necessarily interested. The class that looks tolerantly at the stereopticon views that the instructor presents, or listens to the reading of the professor of English, is amused but not necessarily interested. But when the students ask questions about the pictures or ask the professor of English for further references, then have we evidence of real interest. Interest is, therefore, an active attitude toward life's experience. Rational motivation is almost a guarantee of this active attitude of interest.

Intelligent motivation in teaching has far-reaching values for both student and teacher. It stirs interest and guarantees attention and thus tends to keep aroused the activity of the students. It establishes an end toward which all effort of teacher and student must bend. It enables the student to follow a line of thought more intelligently, and occasionally to anticipate conclusions. For the teacher it serves as a standard, in terms of which he reorganizes his subject matter, judges the value of each topic, and omits socially useless matter which has too long been retained in the course in the fond hope that it will in some way develop the mind.

=Beginning at the point of contact=

The instructor who strives to motivate the subject matter he teaches usually begins with that phase of the subject which is most intimately related to the student's life and environment. Every subject worth teaching crosses the student's life at some point. The contacts between pupil and subject afford the most natural and the most effective starting points in the teaching of any subject.

The subject matter in a college course is too frequently so organized that it presents points of discrepancy between itself and the student. To the college student life is not classified and systematized to a nicety. Experiences occur in more or less accidental but natural sequence. Scientific classification is the product of a mature mind possessing mastery of a given portion of the field of knowledge. To thrust the student, who is just finding his way in a new course, into a thoroughly scientific classification of a subject, is to present in the introduction what should come in the conclusion.

Many a student taking his introductory course in psychology begins with a definition of the subject, its relation to all social and physical sciences, and its classification. All these are aspects of the subject which the mind conversant with it sees clearly and understands thoroughly, but which the inexperienced student accepts merely because the facts are printed in his textbook. The youthful mind is concerned with the present and with the immediate environment. Too many of our college courses, in the initial stages, transport the student into the realm of theory or into the distant past. The student cannot orientate himself in this new environment and is soon lost on the highways and byways of classification; to him the subject becomes a study of words rather than of vital ideas. Why must the introductory course in philosophy begin with the ancient philosophers, and give the major part of the term to the study of dead philosophers and their theories long since refuted and discarded, while vital modern philosophic thought is crowded into the last few sessions of the semester?

=Illustrations of maxim. Begin at the point of contact=

The pedagogical significance of beginning at the point of contact can best be understood and appreciated by illustrations of actual teaching conditions. Most initial courses in economics begin by positing that economics is the science of the consumption, distribution, and production of wealth. The student is told that in earlier systems of economics production was studied as the initial economic process, but that the more modern view makes consumption the starting process. All this the student takes on faith. He does not really see its bearings and its implications; he is as unconcerned with the new formulation as he is with the old; he feels at once far removed from economics. The succeeding lessons study economic laws with little reference to the economic life that the student lives. In a later chapter he learns a definition of wages, the forces that determine wage, and the mode of computing the share of the total produce that must go to wages.

Here we have a course that does not begin at the point of contact, that presents the very discrepancies between itself and the student that were noted before. How can we overcome them? By proceeding psychologically. The instructor refers to two or three important wage disputes in current industrial life; these conflicts are analyzed; the contending demands are studied, and the forces controlling the adoption of a new wage scale are noted. After this study of actual economic conditions the students are led to formulate their own definition of wages, and to discover the forces that determine wage. Their conclusions are of course tentative. The textbook or textbooks are consulted in order to verify the formulations and the conclusions of the class. Thus the course is developed entirely through a series of contacts with economic life. The final topic in the course is the formulation of a definition of economics. Now the class sums up all that it has seen and learned of economics during the year. The cold and empty definition now glows with meaning. Such a course awakens an intelligent interest in economic life; it develops a mode of thought in social sciences and a sense of self-reliance; it teaches the student that all conclusions are tentative and constantly subject to verification; it fosters a critical attitude toward printed text.

The college graduate who studied college mathematics, advanced algebra, trigonometry, analytical geometry, and calculus, looks back with satisfaction at work completed. Each of these subjects seemed to have little or no relation to the other; each was kept in a water-tight compartment. He remembers few, if any, of the formulæ, equations, and symbols. He recalls vividly his admiration of the author's ingenious method of deriving equations. Every succeeding theorem, formula, or equation was another puzzle in a subject which seemed to be composed of a series of difficult, unrelated, and unapplied mathematical proofs. The course ended, the mass of data was soon obliterated from the mind's active possessions.

What is the meaning of it all? What is its relation to life? There is no doubt that much of this mathematics has its application to life's needs, and that these successive subjects of mathematics are thoroughly interdependent. But nothing in the mode of instruction leads the student to see either the application or the interrelation of all this higher mathematics. Would it not be better to give a single course called mathematics rather than these successive subjects? Would it not be more enlightening if each new mathematical principle were taught through a situation in building, engineering, or mechanics so that the student would at all times see the intimate relation between mathematical law and physical forces? Would not the disciplinary values of mathematics be intensified for the student by teaching it in a way that presents a quantitative interpretation of the daily phenomena in his experience?

Teachers of philosophy and psychology too often fall into a formalism that robs their subject of all its vitalizing influences. Many a student enters his course in logic with high hopes. At last he is to learn the laws of thought which will render him keen in detection of fallacies and potent in the presentation of argument. How bitter is his disappointment when he finds his course dissipated in definitions and classifications. His logic gives itself to the discussion of such patent fallacies as, "A good teacher knows his subject; Williams knows his subject, therefore he is a good teacher." Day after day he proves the error in every form of stupidity or the truth of what is axiomatic. He tires of "Gold is a metal" and "Socrates is mortal." Few courses in logic have the courage to break away from the traditional formalism and to begin each new principle or fundamental concept of logic by analyzing editorials, arguments, contentions in newspapers, magazines, campaign literature, or the actual textbooks. Few students complete their course in logic with a keener insight into thought and with a maturer or more aggressive mental attitude.

=Beginning at the point of contact relates the subject to the life of the student=

It was pointed out in a previous illustration that the college student "taking philosophy" is seldom made to feel that the subject he studies is related to the problems that arise in his own life. Too frequently introductory courses in philosophy are historical and extensive in scope, striving to develop mastery of facts rather than to give new viewpoints. The student learns names of philosophers, and attempts to memorize the philosophic system developed by each thinker. Such a course imposes a heavy burden on retentive power, for no little effort is required to remember the distinctive philosophical systems advocated by the respective writers. To the students these philosophers represent a group of peculiar people differing one from the other in their degrees of "queerness." One system is as far removed as another from the life that the student experiences; no system helps him to find himself. An introductory course in philosophy should begin with the problems of philosophy; it should have its origin in the reflective and speculative problems of the student himself. As the course progresses, the student should feel a growing sense of power, an increasing ability to formulate more clearly, to himself at least, the questions of religion and ethics that arise in the life of a normal thinking person. So, too, courses in ethics and psychology lose the vital touch unless they begin in the life of the student and apply their lessons to his social and intellectual environment.

It must be pointed out, however, that the social sciences lend themselves more readily to this intimate treatment than do languages, or the physical sciences, but at all points possible in the study of a subject, the experience of the student must be introduced as a means of giving the subject real meaning. In teaching composition and rhetoric illustrations of the canons of good form need not be restricted to the past. Current magazines and newspapers are not devoid of effective illustrations. When the older literary forms are used exclusively as models of language, the student ends his course with the erroneous notion that contemporary writing is cheap and sensational and devoid of artistic craftsmanship.

Courses in physics and chemistry frequently devote themselves to a development of principles rather than to the applications of the studies to every sphere of life. Introductory college courses in zoölogy spend the year in the minutiæ of the lowest animal forms and rarely reach any animal higher in the scale than the crayfish. We still find students in botany learning the various margins of leaves, the system of venation, the scientific classifications, but at the end of the course, unable to recognize ordinary leaves and just as blind to nature as they were before. Zoölogy and botany do not always--as they should--give a new view of life, a new attitude towards living phenomena, a new contact with nature.

Careful inquiry among college students will reveal an amazing ignorance of common chemical and physical phenomena after full-year courses in chemistry and physics. We find a student giving two semesters to work in each of these subjects. He spends most of his time learning the chemical elements, their characteristics and the modes of testing for them. The major portion of the time is spent in the laboratory, where he must discover for himself the elementary practices of the subject and test the validity of well-established truths. At the end of his second semester he has not developed sufficient laboratory technique for significant work in chemistry; he is ignorant of the chemical explanation of the most common phenomena in life.

=Pedagogical vs. logical organization=

There is much to be said for the position taken by the "older teachers," who may not possess the scholarship of the "younger investigators" but who argue for a general course in which laboratory work shall be reduced, technique minimized, and attention focused on giving an extensive view of chemical forces. The simple chemical facts in digestion, metabolism, industry, war, medicine, etc., would be presented in such a way as to make life a more intelligent process and to give an insight into the method of science. In the courses that follow the introductory one, there would be a marked change in aim; the student would be taught the laboratory technique and would be given a more intensive study of the important aspects of chemistry. Similar changes in the introductory courses in physics are urged by these same teachers.

Beginning at the point of contact may frequently interfere with the logical arrangement of the course of study; it may wrench many a topic out of its accustomed place in the textbook; it will demand that the applications, which come last in most logically arranged courses, be given first and that definitions and principles which come first be given last. This logical arrangement, it was pointed out, is usually the expression of the matured mind that is thoroughly conversant with every aspect of a subject; it may mean little, however, to the beginner--so little that he does not even slightly appreciate its significance. The loss in logical sequence entailed by beginning at the point of contact is often more than compensated for by the advantages which are derived from a psychological presentation.

=Proper organization as a factor in effective teaching=

A well-organized lesson possesses teaching merits which may counteract almost all the usual weaknesses found in poor teaching. Good organization determines clearness of comprehension, ease of retention, and ability of recall; it makes for economy of time and mental energy; it simplifies the processes of mental assimilation; it teaches the student, indirectly but effectively, to think sequentially. We have all suffered too keenly, as auditors and readers, the inconveniences of poor organization, not to realize the worth of proper organization of knowledge in teaching.

Organization of knowledge has become a pedagogical slogan, but its increase in popularity has not been accompanied by increased clearness of comprehension of its meaning. What, then, is meant by proper organization? It must ever be borne in mind that proper organization is a relative condition, the limits of which are determined by the capacities of the students and the nature of the subject matter. What is effective organization of facts in elementary history may be very ineffective organization for students of high school or college grade. Making due allowance for relative conditions, good organization may be said to consist of five essential characteristics.

_Logical sequence_ is the first of these. It is apparent that the more rational the sequence of facts, the more effective is the organization of knowledge. Data organized on a basis of cause and effect, similarity, contrast or any other logical relationship will help to secure the teaching advantages we have mentioned. A search for this simple principle in most textbooks on American or English history or literature reveals its complete absence. A detailed mass of historical information grouped into administrations or reigns is merely a mechanical organization in which time, the accidental element, and not the development of social movements, the logic of human history, is the determining factor. In too many courses in literature the student learns names of writers, biographical data, and literary characteristics of the masters, but fails to see the development of the movement of which the writer was a part. Events of history placed in their social movements, writers in literature placed in the school in which they belong, give the student the logical ties which bind the knowledge to him. So, too, one often analyzes the sequence of chapters in an advanced algebra or a trigonometry and fails to discover the governing rationale. It must be remembered, however, that the nature of the subject will often reduce the logical element in its organization. Instances in language teaching may be cited as illustrations of teaching situations where a mechanical organization is often the only one possible because of the arbitrary character of the subject matter.

=Meaning of organization of subject matter=

_Relativity_ of importance is the second factor of good organization. A cursory study of a well-organized chapter or merely passing attention to a well-organized lecture reveals at once a distinct difference in the emphasis on the various parts or elements of the subject. The proportional allotment of time or space, the number of illustrations, the number of questions asked on a given point, the force of language--these are all means of bringing out the relative importance of constituent topics or principles. In retrospect, a well-organized lesson presents an appearance similar to a contour map; each part stands out in distinctive color according to its significance.

It is frequently argued by teachers that students of college age should be required to distinguish the relativity of importance of the parts of a lesson or the topics in a subject; that the instructor who points out the changing importance of each succeeding part of a lesson is enervating the student by doing for him what he ought to do for himself. This is true in part, but it must be realized that the instructor who through questions and directed discussions leads students to formulate for themselves the relative importance of data is not only carrying out the suggestion made in the preceding paragraph but is also developing in his students a power they too frequently lack. Those who have studied the notes that students take in their classes have seen how frequently facts are torn from their moorings; how wrong principles are derived from illustrations; how a catch-phrase becomes a basic principle; how simple truths and axioms are distorted in the frenzy of note taking. Through questions if possible, through emphasis on illustrations and explanations, where no other means is available, students must be made to see that all facts of a subject are not of the same hue, that some are faint of tint, others in shadow, and still others in high colors. Without this relativity of importance, facts are grouped; with it, they are intelligently organized.

_An underlying tendency_ can be discerned in well-organized knowledge. Not only are facts arranged in logical sequence and emphasized according to importance, but there is in addition a central principle or an underlying purpose giving unifying force to them all. We can illustrate the need of this third characteristic of good organization by referring to a college course in American history which gives much time to the period from 1815 to 1860. The events of these forty-five years are not taught in administrations but are summed up in six national tendencies; viz., the questions of state sovereignty, slavery, territorial acquisition, tariff, industrial and transportational progress, and foreign policy. Each of these movements is treated as intensively as time permits. At the end of the study of the entire period, the student is left with these six topics but without a unifying principle; to him, these are six unrelated currents of events. In each of these problems the North and the South displayed distinctive attitudes, acted from distinctive motives, expressed distinctive needs and preferences, but these were never brought out either through well-formulated questions or through explanation. As a result, the class never realize fully that those years, 1815-1860, marked the period of growing sectional differences, misunderstandings, and animosities. Had this underlying tendency been brought out clearly at various points in the course, the students would have carried away a permanent impression of what is most vital in this period of American development.

_Gradation_ of subject matter is another characteristic of good organization. Careful gradation is not so vital in subjects of social content as it is in mathematics, foreign languages, and exact sciences. The most important single factor in removing difficulties that beset a student is gradation. Teaching problems often arise because the instructor or the textbook presents more than one difficulty at a time. Teachers who lack intellectual sympathy or who are so lost in the advanced stages of their specialty that they can no longer image the successive steps of difficulty, one by one, that present themselves to a mind inexperienced in their respective fields, are frequently guilty of this pedagogical error. Malgradation of subject matter is the direct cause of serious loss of time and energy and of needless discouragement not only to students but to instructors as well.

_Ability of the student to summarize_ easily is a test of good organization. At the end of a loosely organized chapter or lesson the student experiences no little difficulty in setting forth the underlying principles and their supporting data. It does not help much to have the textbook or the instructor state the summary either at the end of the lesson in question or at the beginning of the succeeding one. The summary of a lesson, given by the class, is a test of the effectiveness of instruction. Summaries given by teachers or textbooks have little or no pedagogical justification. Only in cases where the summary introduces a new point of view or unifying principles, or when it sets forth basic principles in particularly forceful language--only then is the statement by teacher or textbook justifiable.

=Thoroughness=

Teachers are advised to be thorough in their instruction. They in turn urge their students to strive for thoroughness in study. We praise or impugn the scholarship of our colleagues because it possesses or lacks thoroughness. Here we have a quality of knowledge universally extolled. But what is meant by thoroughness? How can teachers or students know that they are attaining that degree of comprehension known as thoroughness? We are told that thoroughness is a relative condition, always changing with accompanying circumstances. Even an unattainable ideal can be defined,--why not thoroughness? We must, therefore, attempt to determine the meaning of thoroughness as used in teaching and study.

=Negative interpretation of thoroughness=

It may be helpful to formulate the common or lay interpretation of thoroughness. The term "thoroughness" is erroneously used in a quantitative sense to describe scholastic attainment. We are told of a colleague's thoroughness in history; he knows all names, dates, places, facts in the development of mankind; his knowledge of his specialty is encyclopedic; "there is no need of looking things up when he is around." A professor of English literature boasted of the thoroughness with which he teaches _Hamlet_: "Every word of value and every change in the form of versification are marked; every allusion is taken up, every peculiar grammatical construction is brought to the attention of the class." Here we have illustrations of an erroneous conception of thoroughness which gives it an extensive meaning and regards it as the accumulation of a mass of data.

=Positive interpretation of thoroughness=

Yet the master of chronological detail in history may have no historical imagination, no historical perspective, no historical judgment. He may possess the facts, but a period in history still remains for him a stretch of time limited by two dates, rather than a succession of years in which all mankind seems to be moving in the same direction, possessed of the same viewpoints, the same hopes and aspirations. The professor of English literature does not see that in teaching _Hamlet_ he forsook his specialty, literature, for philology and mythology; that he turned his back on art and took up language structure. Thoroughness is not completeness, because the possession of the details of a subject does not necessarily bring with it a true comprehension of it. Add all the details, and the sum total is nothing more than the group of details. Thoroughness is a degree of comprehension resulting from the acquisition of new points of view. The teacher of history who sees underlying forces in the facts of the past, who understands that true inwardness of any movement which shows him its relation to all phases of life, but who nevertheless may not have ready command of all the specific details, is more thorough in his scholarship. He has the things that count; the facts that are forgotten can easily be found. The class that studies the dramatic structure of _Hamlet_, that sees Shakespeare's power of character portrayal, that takes up only such grammatical and language points as give clearer comprehension or lead to greater appreciation of diction, is thorough although it does not possess all the facts. It is thorough because what is significant and dynamic in _Hamlet_ is made focal. The postgraduate student assiduously searching for data for his doctorate thesis is often guided by the erroneous conception of thoroughness; he wants facts that have never seen the light. The more he gets of these, the nearer he approaches his goal. He avoids conclusions; he is counseled by his professors against giving too much of his book to the expression of his views. Analyze the chapters of a doctorate thesis and note the number of pages given to facts and those to conclusions and interpretations. The proportion is astonishing. The student's power to find facts is clearly shown; his power to use facts is not revealed by his thesis. The richer the thesis is in detail, in references, in allusions to dusty tomes and original sources, the more thorough is it frequently considered by the faculty. We have failed to realize that this excessive zeal in gathering and collating a large number of not commonly known facts may make the thesis more cumbersome, more complete, but not necessarily more thorough. However, the plea for a new standard in judging doctorate theses is meeting with gratifying encouragement.

What, then, are the teaching practices that make for greater thoroughness, that increase the qualitative and intensive character of knowledge? We shall discuss some of these in the succeeding paragraphs.

=How can thoroughness be produced?=

The _acquisition of new points of view_ makes for increased thoroughness of comprehension. The class that understands the causes of the American Revolution from the American point of view knows of the navigation laws, the quartering of soldiers in American homes, the Stamp Act, the Boston Massacre,--the usual provocations that strained patience to the breaking point. The college teacher of American history who spends time on the riots in New York in which a greater number of colonists was killed than in Boston, who teaches in detail the various acts forbidding the manufacture of hats and of iron ware, or the protests against English practices in the colonies made by British merchants, etc., is adding more facts, but he may only be intensifying the erroneous conclusion that the students have formed in earlier and less complete courses. The topic, "Causes of the American Revolution," grows in thoroughness, not through the addition of these facts but through the presentation of new interpretations of the practices of the English. When we explain that the English believed in virtual and not actual representation, the students see a new meaning in "taxation without representation." When the students learn that the English government decided on a new economic and industrial policy which planned to have the mother country specialize in manufacture and transportation and the colonies in production of raw materials, the students see reason, though not necessarily justice, in the acts prohibiting Americans from various forms of manufacture and transportational activities. These new facts modify in the minds of students the point of view so often given in elementary courses, that the War for Independence was caused by sheer British meanness and injustice, by her policy of reckless repression.

It is not always possible to give new points of view to all knowledge in all subjects. There are cases in which there is only one point of view or where students may not be ready for a new interpretation because of their limited mastery of a new field of knowledge. Under these conditions an added point of view is a source of confusion rather than an aid to clearer comprehension. Some subjects, like the social sciences, naturally allow for richer interpretations. Others, like the languages and the physical sciences, present only very limited opportunities; in the biological sciences the possibilities, though not as rich as in the social sciences, are numerous and productive of good results.

_Comparison_ is a second means of producing thoroughness of comprehension. Good teaching abounds in comparisons which are introduced at the end of every important topic rather than reserved for examination questions. Comparisons used liberally at every logical pause in the development of a subject always give an added viewpoint, review early subject matter incidentally, stir thought, and make for better organization. How much more clearly are the causes of the War of 1812 understood after they are compared with those that brought on the Revolutionary War! How much more definite are the causes of the American Revolution when compared with those that brought on the French Revolution! A writer, a school, or a movement in English literature may be understood when studied by itself; but how is comprehension deepened when each is compared with another writer or school or movement! Comparison of perception and conception or appreciation and association in psychology, makes each activity stand out clearer in the mind of the student. Compare the laws of rent, wage, profit, and interest in economics, and not only each is better understood but the basic laws of distribution are readily derived by the student. Similarly, comparisons in mathematics, physics, chemistry, and the entire range of collegiate subjects give increased comprehension, useful though incidental reviews, and greater unification of knowledge, as well as added points of view.

_Correlation_ as a means of producing thoroughness is closely allied to comparison. Correlation relates kindred topics of different subjects, while comparison points out relations in the same subject. The instructor who correlates the history of education with the political and economic history that the student learned in another course is unifying related experience, reducing the field of knowledge, introducing logical organization, and adding new interpretations to facts already acquired. Similarly, teaching must be enriched by correlating physics and mathematics, chemistry and physics, literature and music, history of literature and general history, until instruction has taken advantage of every vital relation among subjects. With the growth of specialized subjects there is an unfortunate tendency toward isolation until the untrained mind looks upon the curriculum as a series of unrelated experiences, each rivaling the other in its claim to importance.

The advantage of correlation will remain lost in college teaching as long as each instructor regards himself as a specialized investigator concerned with teaching his subject rather than his students. How many college teachers know what subjects their students have already taken, or knowing the names of these subjects, have a general knowledge of their content? The college professor of the preceding generation was a cultured gentleman whose general scholarship transcended the limits of his specialty. He understood and knew the curriculum as a whole. Because of changes in every phase of our civilization, his successor has a deeper but a narrower knowledge. He knows little of the work of his students outside of his own subject. He does not relate and correlate the ever growing field of knowledge; he merely adds--by the introduction of his own mass of facts--to the isolation which characterizes the parts of college curricula. This tendency must be counteracted, not by interfering with the scholastic interests of any instructor, but by occasional conferences of instructors of allied subjects in order to agree on common meeting grounds, on points of correlation, on useful repetitions, and on the elimination of needless duplications. Such pedagogical conferences are rare because college teachers are not alive to the need of reform in methods of college teaching.

Thoroughness results from _increase in the number of applications_ of knowledge. The introduction of the functional view into teaching brings with it a realization of the vital needs of increased ways of applying the experience we present to students. As the laws of physics, mathematics, biology, composition, economics, etc., are applied to a number of specific instances, the generalization grows in meaning and in force. Specific cases vary, and, varying, give new color and new meaning to the laws that are applied to explain them. How much a law in chemistry means after it is applied to specific instances in industry, human and animal physiology, plant life, or engineering! The equation learned in descriptive geometry may be understood, but it never means so much as when it is applied to specific problems in engineering. Applications give added insight into knowledge and therefore make for greater thoroughness of comprehension.

=Teaching as a process of arousing self-activity=

Locke's Blank Paper Theory, enunciated centuries ago, has been repeatedly and triumphantly refuted even by tyros in psychology, but in educational practices it continues to hold sway. College teaching too frequently proceeds on the assumption that the mind is an aching void anxiously awaiting the generous contributions of knowledge to be made by the teacher. College examinations usually test for multiplicity of facts acquired, rather than for power developed. College teaching usually does not perceive that the mind is a reacting machine containing a vast amount of pent-up potential energy which is ready to react upon any presentation; that development takes place only as this self-activity expresses itself; that education is evolutionary rather than involutionary. Teaching is, therefore, a process of arousing, sustaining, and directing the self-activity of pupils. The more persistently and successfully this activity is aroused, the more systematically it is directed to intelligent ends, the more skillful is the teaching. Teachers do not impart knowledge, for that is impossible; they _occasion_ knowledge. Only as the teacher succeeds through questions, directions, diagrams, and all known devices, in arousing the self-activity of the student, is he producing the conditions under which knowledge is acquired by the pupil.

=Evaluation of common methods of teaching=

The methods commonly used in college teaching are as follows:

1. Lecture method, with or without quiz sections.

2. Development method, with or without textbook.

3. Combination of lecture and development method.

4. Reference readings and the presentation of papers by students.

5. Laboratory work by students, together with lectures and quiz sections.

Teachers have long debated the relative merits of these methods or combinations of them. They fail to realize that each method is correct, depending upon the aim to be accomplished and the governing circumstances. No method has a monopoly of pedagogical wisdom; no method, used exclusively, is free from inherent weakness. A teaching method must be judged by its ability to arouse and sustain self-activity and to attain the aim set for a specific lesson. With this standard for judging a method of teaching, we must stop to sum up the relative worth of common methods of college teaching.

=Lecture method evaluated=

The _lecture method_ has been the target for much criticism for many centuries. Socrates inveighed against its use by the sophists, and educators since have repeated the attack. The reasons are legion: (_a_) The lecture method tends to discourage the pupil's activity. The student feels no responsibility during the lecture; he listens leisurely, and makes notes of the instructor's contribution. The student's judgment is not called into play; he learns to take knowledge on the authority of the instructor. The sense of comfort and security experienced in a lecture hour is fatal even to aggressive and assertive minds. Sooner or later the students succumb to the inertia developed by the lecture system.

(_b_) A second limitation of an exclusive lecture method is its inability to make permanent impressions. Many a student, entering the lecture hall, has completely forgotten even the theme of the last lecture. Knowledge is retained only when it is obtained by the expression of self-activity. To offset this weakness notes must be taken, but these prove to be the bane of the lecture method. Some students, in their efforts to record a point just concluded, lose not only the thought of what they are trying to write but also the new thought which the instructor is now explaining; they drop both ideas from their notes and wait for the next step in the development of the lecture. This accounts for the many gaps in the notes kept by students. Some instructors, dismayed by the amount of knowledge lost by students, resort to dictation devices. Others, realizing the pedagogical weakness of such teaching, distribute mimeographed outlines of carefully prepared summaries of the lectures. Now the student is relieved of the tedium of note taking, but the temptation to let his mind wander afield is intensified. An outline, scanty of detail, but so devised as to keep the organization and sequence of subject matter clear in the minds of students, is, of course, helpful. But detailed outlines distributed among the students discourage even attentive listening.

(_c_) In teaching by lectures only there is no contact between student and teacher. The student does not recite; he does not reveal his type of mind, his mode of study, his grasp of subject matter. He is merely a passive recipient. To this third weakness of the lecture method we may add a fourth: (_d_) it tends to emphasize quantity rather than method. The student is confronted with a great mass of facts, but he does not acquire a mode of thought nor does he see the method by which a given subject is developed. (_e_) The lecture method, therefore, inculcates in students an attitude of mental subservience which is fatal for the development of courageous and vigorous thought. And finally (_f_) it must be urged that in lecture teaching the instructor is not testing the accuracy of the students' conceptions nor is he able to judge the efficacy of his own methods.

But, on the other hand, it must be admitted that with an effective lecturer, possessed of commanding personality, the lecture gives a point of view of a subject and an enthusiasm for it which other devices fail to achieve. The lecture method makes for economy of time and enables one to present his subject to his class with a succinctness absent from many textbooks. Where much must be taught in a limited time, where a comprehensive view of an extensive field must be given, when certain types of responses or mental attitudes are desired, the lecture serves well.

=Final worth of lecture method=

Experience teaches that an exclusive lecture system is not conducive to efficient work; that lectures to regular classes ought to be punctuated by questions whenever interest lags; that the occasional and even the unannounced lecture is more effective; that supplementary devices for checking up assignments and regular collateral study are of vital importance. Where regular lectures are followed by detailed analyses in quiz sections the best results are obtained when the lecturer himself is the questioner. Where quiz sections are turned over to assistants, wise procedure requires that quiz leaders attend the lectures and decide, in conference with the lecturer, the specific aims which must be achieved in the quiz work and the assigned readings which must be given to students in preparation for each quiz hour. Unless this is done, the student is frequently confused by the divergent points of view presented by lecturer, quiz master, and textbook.

_The development method_ has much to commend it. It stimulates activity by its repeated questions. Few or no notes are taken. There is constant contact with the student. At every point the mental content of the pupils is revealed. The teacher sees the result of his teaching by the intelligence of successive responses. The pupil is being trained in systematic thought and in concentration. But it must be remembered that the development method is often costly in time because answers may be wrong or irrelevant. It may encourage wandering; a student's reply reveals ignorance of a basic principle, and the aim of the lesson is often forgotten in the eagerness to patch up this misconception. Then, too, in subject matter that is arbitrary, as in descriptive and narrative history, no development is possible. In such cases the questions are designed to test the student's knowledge of the text, and the lesson becomes a quiz rather than a development.

It is plain, therefore, that a judicious combination of the lecture and development methods will give better results than the exclusive use of either one. The analysis of the pedagogical advantages of each leads to the conclusion that the development method should predominate and that the lecture method should be used sparingly and always with some of the checking devices described.

=Place of reference reading in college teaching=

=Evaluation of development--Socratic or heuristic method=

A common method employed in advanced courses in college subjects emphasizes _reference study and research_. The entire course is reduced to a series of problems, each of which deals with a vital aspect of the subject. Each student is made responsible for a topic. The initial hours are devoted to an examination of the common sources of information in this specific subject, the modes of using these, the standards to be attained in writing a paper on one of the topics, and similar matters. The remainder of the term is given over to seminar work: each student reads his paper and holds himself in readiness to answer all questions his classmates may ask on his topic. The aims of such a course are obviously to develop a knowledge of sources and an ability to use intelligently the unorganized data found by the student. The results of these pseudo-seminar courses are far from what was anticipated. A thorough investigation of such a course will soon convince the teacher that the seminar method, whatever its merits in university training, must be refined and diluted before it is applied to college teaching. Let us see why.

Successful reference reading requires a knowledge of the field studied, maturity of mind, discriminating judgment in the selection of material, and ability in organization. The university student is not only maturer and more serious but has a basis of broader knowledge than most undergraduates. Without this equipment of mental powers and knowledge, the student cannot judge the merits of contending views nor harmonize seeming discrepancies. A student who has no ample foundation of economics cannot study the subject by reference reading on the problems of economics. To learn the meaning of value he would read the psychological explanations of the Austrian schools and the materialistic conceptions of the classical writers. He would then find himself in a state of confusion, owing to what seemed to him to be a superfluity of explanations of value. When one understands one point of view, an added viewpoint is a source of greater clarity and a means of deeper understanding. But when one is entirely ignorant of fundamental concepts, two points of view presented simultaneously become two sources of confusion. In the university only the student of tried worth is permitted to take a seminar course. In the upper classes in college, mediocre students are often welcomed into a seminar course in order to help float an unpromising elective.

=Limitations of seminar method in undergraduate teaching=

The college seminar is usually unsuccessful because few students have ability to hold the attention of their classmates for a period of thirty minutes or more. Language limitations, lack of a knowledge of subject matter, inability to illustrate effectively, and the skeptical attitude of fellow students all militate against successful teaching by a member of the class. Students presenting papers often select unimportant details or give too many details. The rest of the class listen languidly, take occasional notes, and ask a few perfunctory questions to help bring the session to a close. A successful hour is rare. The student who prepared the topic of the day undoubtedly is benefited, but those who listen acquire little knowledge and less power. The course ends without a comprehensive view of the entire subject, without that knowledge which comes from the teacher's leadership and instruction. This type of reference reading and research has value when used as an occasional ten or fifteen minute exercise to supplement certain aspects of class work. But as a steady diet in a college course, the seminar usually leaves much to be desired.

The _laboratory method_ is growing in favor today in college teaching. It is employed in the social sciences, in sociology, in economics, in psychology, in education, as well as in the physical and the biological sciences. Where it is followed the aim is clearly twofold; viz., to teach the method by which the specific subject is growing and to develop in the students mental power and a scientific attitude towards knowledge.

=Value of laboratory method=

Let us illustrate these two aims of the laboratory method. A laboratory course in chemistry or biology or sociology may be designed to teach the student the use of apparatus and equipment necessary for work in a respective field; the method of attacking a problem; a standard for distinguishing significant from immaterial data; methods of gathering facts; the modes of keeping scientific records,--in a word, the essence of the experience of successive generations of investigators and contributors. But no successful laboratory results can be obtained without a proper mental attitude. The student must learn how to prevent his mental prepossessions or his desires from coloring his observations; to allow for controls and variables; to give most exacting care to every detail that may influence his result; to regard every conclusion as a tentative hypothesis subject to verification or modification in the light of further test. Unless the student acquires a knowledge of the method of science and has achieved these necessary modes of thought, his laboratory course has failed to make its most significant contribution.

In courses where the aim is to teach socially necessary information or to give a comprehensive view of the scope of a specific subject, it is obvious that the laboratory method will lead far afield. It is for this reason that introductory courses given in recitations, with demonstrations by instructors, and occasional lecture and laboratory hours, are more liberalizing in their influence upon the beginners than courses that are primarily laboratory in character.

=Cautions in the use of the laboratory method=

Most laboratory courses would enhance their usefulness by observing a few primary pedagogical maxims. The first of these counsels that we establish most clearly the distinctive aim of the course. The instructor must be sure that he has no quantitative aim to attain but is occupied rather with the problems of teaching the method of his specialty. Second, an earnest effort must be made to acquaint the students with the general aim of the entire course as well as with the specific aim of each laboratory exercise. The students must be made to realize that they are not discovering new principles but that by rediscovering old knowledge or testing the validity of well-established truths they are developing not only the technique of investigational work, but also a set of useful mental habits. Much in laboratory work seems needless to the student who does not perceive the goal which every task strives to attain.

A third requisite for successful laboratory work requires so careful a gradation that every type of problem peculiar to a subject is made to arise in the succession of exercises. It is wise at times to set a trap for students so that they may learn through the consequences of error. For this reason students may be permitted to leap to a conclusion, to generalize from insufficient data, to neglect controls, to overlook disturbing factors, etc. An improperly planned and poorly graded laboratory course repeats exercises that involve the same problems and omits situations that give training in attacking and solving new problems.

Effective laboratory courses afford opportunity to students to repeat those exercises in which they failed badly. If each exercise in the course is designed to make a specific contribution to the development of the student, it is obvious that merely marking the student zero for a badly executed experiment is not meeting the situation. He must in addition be given the opportunity to repeat the experiment in order to derive the necessary variety of experiences from his laboratory training. And, finally, the character of the test that concludes a laboratory course must be considered. The test must be governed by the same underlying aims that determine the entire course. It must seek to reveal, not the mastery of facts, but growth in power. It must measure what the student can do rather than what he knows. A properly organized test serves to reinforce in the minds of students the aims of the entire course.

=The college teacher not the university professor=

An analysis of effective teaching is necessarily incomplete that does not give due consideration to the only human factor in the teaching process--the teacher. We have too long repeated the old adages: "he who knows can teach"; "a teacher is born, not made"; "experience is the teacher of teachers." These dicta are all tried and true, but they have the failings common to platitudes. It often happens that those who know but lack in imagination and sympathy are by that very knowing rendered unfit to teach. "Knowing" so well, they cannot see the difficulties that beset the learner's path, and they have little patience with the student's slow and measured steps in the very beginnings of their specialty. It is true that some are born teachers, but our educational institutions could not be maintained if classes were turned over only to those to whom nature had given lavishly of pedagogical power. Experience teaches even teachers, but the price paid must be computed in terms of the welfare of the student. Teaching is one of the arts in which the artist works only with living material; yet college authorities still make no demand of professional training and apprenticeship as prerequisites for admission to the fraternity of teaching artists.

Ineffective college teaching will not improve until professional teaching standards are set up by respected institutions. The college teacher must be possessed of ample scholarship of a general nature. He must have expertness in his specialty, to give him a knowledge of his field, its problems and its methods. He must be a constant student, so that his scholarship in his specialty will win recognition and respect. But part of his preparation must be given over to professional training for teaching. Without this, the prospective teacher may not know until it is too late that his deficiencies of personality unfit him for teaching. With it, he shortens his term of novitiate and acquires his experience under expert guidance. The plan of college-teacher training, given by Dr. Mezes in Chapter II, so complete in scope, so thoroughly sound and progressive in character, is here suggested as a type of professional preparation now sorely needed.

=Testing the results of instruction=

The usual test of teacher and student is still the traditional examination, with its many questions and sub-questions. We still measure the results of instruction by fathoming the fund of information our students carry away. But these traditional examinations test for what is temporary and accidental. Facts known today are forgotten tomorrow. The professor himself often comes to class armed with notes, but he persists in setting up, as a test of the growth of his students, their retentivity of the facts he gave from these very notes. In the final analysis, these examinations are not tests. The writer does not urge the abolition of examinations, but argues rather for a reorganized examination that embodies new standards. A real examination must test for what is permanent and vital; it must measure the degree to which students approximate the aims that were set up to govern the entire course; it must gauge the mental habits, the growth in power, rather than facts. Part of an examination in mathematics should test students' ability to attack new problems, to plan a line of work, to think mathematically, to avoid typical fallacies of thought. For this part of the test, books may be opened and references consulted. In literature we may question on text not discussed in class to ascertain the students' power of appreciation or of literary criticism. So, too, in examinations in social sciences, physical sciences, foreign languages, and biological sciences, the examination must consist, in great measure, of questions which test the acquisition of the habits of thought, of work, of laboratory procedure--in a word, the permanent contribution of any study. This part of an examination should be differentiated from the more mechanical and memory questions which seek to reveal the student's mastery of those facts of a subject which may be regarded as socially necessary. Reduce the socially necessary data of any subject to an absolute minimum and frame questions on it demanding no such slovenly standard--sixty per cent--as now prevails in college examinations. If the facts called for on an examination are really the most vital in the subject, the passing grade should be very high. If the questions seek to elicit insignificant or minor information, any passing mark is too high. It is obvious, therefore, that a student should receive two marks in most subjects,--one that rates power and another that rates mere acquisition of facts. The passing grade in the one would necessarily be lower than in the other. An examination is justified only when it is so devised that it reveals not only the students' stock of socially useful knowledge but also their growth in mental power.
